Leading Dairy Producer Enhances Combustion With Autoflame Existing Equipment: Boilers in need of reducing and monitoring emissions Solution: Autoflame Mk7 MM Controller and Autoflame Mk7 Exhaust Gas Analysers (EGA) Benefits: • Enhanced monitoring of various exhaust gasses • Adjustments to combustion configuration for optimum performance • Unique 3 parameter trim control to maintain commissioning values • Data display for analysis • Increased efficiency • 2% Reduction in O2 levels Arla Foods is one of the UK’s leading dairy companies, processing approximately two billion litres of milk a year and supplying a third of the nation’s milk. Arla works closely with all the major retailers, and has a portfolio of some of the UK’s leading dairy brands including Lurpak, Anchor, Cravendale and Lactofree. Stourton Dairy is one of Arla Foods flagship production facilities. The project brief for this site was to improve efficiency by upgrading to the Autoflame Mk7 Controller and installing Mk7 Exhaust Gas Analysers (EGA) on each boiler to monitor and reduce exhaust gas emissions. It is important for Arla Foods to maintain the efficiency of the company’s manufacturing process and a solution was needed to reduce and monitor emissions from the boiler plant at Stourton. High levels of O 2 within a boiler can have a negative effect on the combustion process, cooling the burner flame and restricting heat transfer to the water. Reductions in O 2 levels will dramatically improve the combustion efficiency. The Autoflame EGA system offers enhanced monitoring of flue gases produced during a combustion process. Six gases can be measured at any one time including O 2 , CO 2 , CO, NO and SO 2 or NO 2 . The system is able to make minor adjustments to the combustion configuration when needed. Unlike other trim systems, Autoflame’s EGA carries out “3 parameter trim” and is used to maintain the commissioning values. CASE STUDY
